Abstract
PURPOSE: To enable to select the sound pressure of sound body with the simple constitution of circuit, by using the transmission gate different in resistance value using MOS transistor between the pulse generating circuit and the high voltage generation circuit.
CONSTITUTION: The pulse generating circuit 1 produces clock pulse with the alarm signal from the clock unit 2 and it is delivered to the transfer line selection circuit 4. The circuit 4 consists of the MOS transistor (MOS Tr)5a and 5b different in ON- reistance and the transfer lines 4a and 4b. On the other hand, the operation signal of the control switch 6 is inverted at FF7, and the output is fed to the gates of MOSTt 5a and 5b via the MOSTr5a and 5b and the inverter 8. The conduction of MOSTr5a and 5b is selected with the operation of the switch 6, and the output of the pulse generating circuit 1 is fed to the coil 10 via either of the circuits different in ON-resistance, producing sound with the vibrator 11. The vibrator produces sound different in the sound pressure depending on the selection of ON-resistance. Thus, the alarm suitable for electronic watches can be established with a simple circuit configuration.
